A night on the tiles refers to pubs in
Sydney Australia. There was a law many years ago that mandated closing of the pubs at 6
pm. The men working locally got off
work at 5 pm and needed to drink as much
beer as they could in 1 hour. If they lost their spot at the
bar to use the toilet, they would lose their chance to drink... causing them to relieve themselves where they stood. After time, the wood foundation of the pub smelled really bad and the wood rotted. The pub owners did repairs and put ceramic tiles up where needed... so they could hose down the waste ... thus drinking heavily.. and a night on the tiles
